摘要
研究了研制的复合外掺料添加含量对机制砂混凝土工作性能和力学性能的影响,并对比了同比例含量下复合外掺料与粉煤灰对混凝土性能的影响。试验结果表明,采用复合外掺料配制混凝土的工作性能和力学性能要优于粉煤灰混凝土,且混凝土的工作性能和力学性能随着复合外掺料含量的增加而逐渐增大,至15%添加含量时接近饱和,继续增加含量,力学性能略有降低。
In this study,the influence of admixture content on the workability and mechanical properties of manufactured sand concrete are investigated.For comparison,the influence of admixture and fly ash with same addition content on the properties of concrete is also studied.Experimental results show that the workability and mechanical properties of admixture concrete is better than fly ash concrete.Workability and mechanical properties of admixture concrete is gradually increasing with the increase of admixture content,until content reaches 15%.Continue increasing the content,mechanical performance slightly reduced.
